Sources of Productivity Growth in U.S. Agriculture in the 19th Century

9408525韦斯这项研究将调查农业生产力增长的来源在十九世纪。这项研究的目标是将每个工人的产出增长分解为四个关键组成部分：工作时间增加，单位时间努力增加，农业产出组成的变化，机械化程度提高和每英亩产量。对劳动力中的男子、妇女和儿童进行了分解分析。 这项研究使用了1820年以及1840年至1900年这十年中每一年的美国劳动力时间序列数据。基本的分析是扩展使用替代估计的劳动力投入，并考虑到劳动力需求，不同地区，等等。 这项研究很重要，因为它确定了农业生产力增长的来源，使我们能够深入了解农业在工业化中的作用，反之亦然。

9408525 Weiss This research will investigate the sources of agricultural productivity growth during the nineteenth century. The goal of the study is to decompose the growth of output per worker into four key components: increased time at work, increased effort per unit of time, shifts in the composition of farm output, increased mechanization, and yield per acre. The decomposition analysis is carried out for men, women and children in the labor force. The study uses time series data on the U.S. labor force for 1820 and each of the decade from 1840 to 1900. The basic analysis is extended using alternative estimates of labor input, and accounting for labor requirements that vary by region, among other things. This study is important because it identifies those sources of agricultural productivity growth that would enable us to gain valuable insights into the role of agriculture in industrialization and vice-versa.
